The current instructions for funannotate sort in the tutorial throw the following error:

funannotate sort -i cleaned.fa -b scaffold -o sorted.fa
88 contigs records loaded
Sorting and renaming contig headers
Traceback (most recent call last):

    if minlen > 0:
TypeError: '>' not supported between instances of 'NoneType' and 'int'

This is because the minlen variable is not being set currently. Therefore, the current version of the code necessitates--minlen 1 argument.

hi so code has already been fixed in the sort routine to default to minlen=0 -- what version are you using of funannotate?

[hyphaltip]

there's no harm in adding this to the tutorial though.

[tayabsoomro]

I am using v1.8.17 downloaded from bioconda.

you can check if /home/intelliyeast/micromamba/envs/funannotate/lib/python3.8/site-packages/funannotate/sort.py looks like https://github.com/nextgenusfs/funannotate/blob/master/funannotate/sort.py

which has minlen=0 in the function initialization
